dynamic in that; they do not change because they are not material and neither are they temporal
or space-related (Waithe, 45). Ideas can be identified and understood because they are ultimate
reality. Ideas subsist as independent beings and objectives of our human conscience. They also
exist as concepts of our human minds. Plans also are the origin of sensible things thus the reason
why Plato does not deny the reality of practical stuff unlike his other counterparts like
Parmenides of Elea who deny sensibility and the occurrence of sensitivity.
The sensible world also referred to as reasonable reality according to Plato’ s philosophy
applies to the world of facts existing individually. These worlds may exist in more than one form
and can always change always like the world of destruction and generation. He explains this
reality as being the area of temporal, spatial, materialistic, and sensible things.
In essence, Plato’ s philosophical thought determines that there are definite universal,
independent things, which differ from the sensible real world. First, Plato argues that science
based on just sensation to discover truth is not possible because it does not change things
scientifically. He gives this notion because science must always be based on a motive, which
studies ideas or nature.
Second, Plato argues that language differs in various geographical areas. He says that
some terms are universally known and often mean a similar idea to most people; therefore, they
should match a concept (Mitchell, 35). For this reason, Plato assumes that there should exist
some universal forms to match the global ideas.
Third, Plato argues that science cannot work with continuously changing things like those
found in a sensible world (Mitchell, 35). It is for this reason that Plato says that science cannot be
used to study practical world knowledge, but instead it can be used to analyze a world that is
immutable. Plato gave an example of an unchanging reality as mathematics and a superior
